SPECIFICATION forming part of Letters Patent No. 760,524, dated May 24,1904.

Application led January 26, 1903. Serial No. 140,643. (No model.)

To all wiz/0771, it may concern:

Be it known that I, ERNEST CRossLEY, a citizen ofthe United States,residing at Canton, in

the county of Stark and State of Ohio, have invented certain'new anduseful Improvements in Conveyers,of which the following is aspecilication, reference being had therein to the accompanying drawings.

Figure 1 is a side elevation of a portion of a conveying apparatussufficient to illustrate the manner of applying my improvements. Fig. 2is a plan View of the parts in Fig. 1. Fig. 3 is a perspective showing'one of the carrier-sections and a part of the guideway. Fig. 4 is aperspective of a part of one of the buckets looking' at it from therear. Fig. 5 is a vertical section of the parts in Fig. 4.

A conveying apparatus constructed in accordance with my improvements maybe loaded by any suitable mechanism. One of the uses to which it isapplicable is the carrying of pigs after they have been cast from moltenmetal, and for purposes of illustration in the present case I haveselected such an apparatus, and in the drawings it is indicated as soarranged as to deliver the pigs of metal to the conveyer.

A indicates a section of a rotary table or carrier of the sort used invpig-casting machines, it having` a framework at B, upon which aresupported a series of molds C, supported in such way that they can beinverted or turned for the purpose of discharging` the pigs therefrom.Not only in such an apparatus, but in others, it is frequently desirablethat the conveyer should carry the loads of material first along' onelevel horizontally and then along another. For instance, depressedchambers, such as are indicated at E and adapted to hold bodies ofwater, can be used.

At F there is shown a substructure-*for inconstruction which constitutethe characteristic matters of the present invention.

The sectlons of the carrler or conveyer are each as an entiretyindicated by 1. As here illustrated, each of theseV sections has a hori-Zontal floor-like part 2 with side walls. The front end has anupwardly-turned wall 4, in which. are formed slots 4`for a purpose to bedescribed.

6 is a bar to which the end wall is secured, the parts outside of theslot being held by hangers or suspension devices 5.

7 indicates a shaft extending across the carrier-section, or it may beformed as a gudgeen-like projection on the bar G. This shaft or theprojection 7 carries the antifriction Wheels or rollers 8 for the upperpart of the carrier-section. A chute-like plate or apron at 9 isprovided, this being rigidly fastened to the front of the carriersection or bar 6 and extending forward to points near the rear end ofthe next adjacent carrier, this chute or wing being adapted to guide thepigs or other loads toward the next carrier-section.

rThe rear end of each carrier has supporting wheels or rollers 11,mounted on shafts or stud-axles 10.

The cars or carrier-sections are advanced by means of propelling-arms1Q, which extend `downward from the rotary part B, each of these armshaving a slotguideway l2, in which is litted the cross-bar 6 of one ofthe carriers and which permits the latter to be raised or lowered whileadvancing under the force imparted by the arms 12.

At 13 13 there are track-irons or supports and guides for the wheels orrollers 8, and at 14 14 there are corresponding guide-irons or tracksfor carrying the wheels 11, these tracks or guides at 13 and 14 beingshown as placed in the relatively higher levels of the path of thecarriers. At 15 17 these tracks are respectively bent downward, thedownwardlyinclined tracks extending therefrom to the lower tracks at 16and 18 for the upper roll ers and lower rollers, respectively, of thecars or carrier-sections. At the place marked X, Fig. 1, the loading ofthe cars or carriersections can be regarded as being effected, some ofthe molds C being indicated by dotted lines as turning over at thispoint in any of the well-known ways. The loads that drop vthe carriersystem, Erst descending over the inclined track-sections to the tracks16 and 18 at the lower level and finally rising again to the tracks at13 14 prior to the unloading.

The unloading of the cars or carrier-sections is effected by depressingor curving downward a part of the tracks or guides 14 at such points asare indicated by 19, the horizontal part of the depressed guides beingshown at 20, and, if required, supports can be provided, as at 21. Vhilethe lower wheels or rollers 11 are following this depressed part of thetrack the upper wheels or rollers 8 are by the upper track 13 heldagainst lowering, and consequently the car or carrier-section attachedto these pairs of rollers is gradually though rapidly tilted in such wayas to permit its load to quickly slide therefrom. Afterward the rollers8 are again brought to their g upper level on the guides 14, and the caror 1,

, tion of the series of carrier elements or seccarrier-section is readyfor reloading.

Instead of a rigid ring-like driving-body,

such as a rotary table or frame at B, use may be made of a fiexibledriver-as, for instance,

an endless chain or cable provided with suitable arms or projectionsanalogous` to those at 12 andarranged in such way as to insure l theconstant application of propelling power p to the cars orcarrier-sections irrespective of the relative horizontal levels on whichthe latter may be traveling.

I am aware that tilting carrier-pans have been connected to endlesschains and employed for the transporting of material from one point toanother, where it is to be deposited, the pans in turn tilting at oneend downward and being guided by downwardly-deflected tracks or guides;but in all cases within my knowledge the pans or conveyer-sections wereeach and all at some point'held in fixed position in relation to thedriving-line of the chain, and guide-Wheels or idler-wheels orequivalent apparatus-for guiding the chain from one level to anotherwere necessary in order to permit the pans or conveyer-sections to thustravel from one level to another.

It lwill be noticed that I employ supporting-tracks and pairs of wheelsVor rollers of different gages, the Wheels 8 8 and their tracks 13 and16 being at a relatively greater distance apart, while the wheels 11 11and their tracks y111 18 are relatively closer together. As a result Iam enabled to always give a positive support to the car, pan, or carriersection at one of its ends and independent of the driving or propellingdevices.v Thus the cars or sections are positively supported by thewheels 8 on the tracks 13 even when they are delivering their loaddownward. In those constructions having chain-drivers within myknowledge the pair of wheels which are held up when the pan or car isemptying are supported by the chains only, and consequently the size andweight of the carrier-sections are limited and strong and expensivechains are necessary, inasmuch as they must not only accomplish thepropulsion but the vertical support of the carrier element.

What I claim is 1. In a conveying apparatus the combination of a drivingdevice moving in relatively fixed lines, a series of carrier-sectionsmovable bodily vertically from one set of lines of travel to another setof lines relatively to the driving device, and propelling devicesinterposedY betweenthe driver and the carrier-sections, substantially asset forth.

2. In a conveying apparatus, the combination with the driving orpropelling device, of a series of carrier-sections receiving propellingpower from the driver and adapted to bodily rise and fall in relation tothe driver while being driven thereby, substantially as set forth.

3. In a conveying apparatus, the combinations, the driving device andthe intermediate power-transmitting devices, the carrier-sections andthe power-transmitters being adapted to rise and fall bodilyv inrelation to each other. v'

11. In a conveying apparatus the combinationof the series ofcarrier-sections each adapted to have one part thereof rise and fall inrelation to the other part thereof, the driving device and theintermediate power-transmitters, the carrier sections being adapted torise and fall bodily in relation to the driver, substantially as setforth.

5. In a conveying system, the combination with the series ofcarrier-sections of the driving device moving in relatively fixed linesand the propelling arms or bars each adapted to engage with one of thecarrier-sections at each of several points varying in their distancesfrom the driving device, substantially as set forth. l

6. In a conveying system, the combination of the series of car-likecarrier-sections each having a load-receiving receptacle and a sheetlikeguide projected toward an adjacent carrier-section, and each adapted tohave one of its ends tilt or rock about an axis adjacent to the otherend, substantially as set forth.

7. In a conveyer system, the combination of the series ofcarrier-sections each adapted to be tilted, substantially as described,for emptying its contents, means for supporting the upper end of eachcarrier-section while tilting and a driving device for advancing thecarrier-sections, said driving device being supported independently ofthe aforesaid supporting devices, substantially as set forth.

8. In a conveyer system, the combination of a series ofcarrier-sections, propelling mechanism therefor, supported independentlythereof, two independent sets of guiding devices,
